C# or VB.net Compatible Data types with Delphi Data Types

[vijay victory]

Hi All, I have created one DLL having some functions as follows.. I want to call them from VB.net and C#.net.

1. Function CONVERTPWDATA ( PASS1,PASS2 : INTEGER; IpStr : PWord; OpStr : PChar;
   LangName : LongInt; AFontType, BFontType : LongInt ) : PChar; StdCall;export;

2. Function CONVERTDATAEX ( PASS1,PASS2 : INTEGER; IpStr : PChar; OpStr : PWord;
   LangName : LongInt; AFontType, BFontType : LongInt ) : PChar; StdCall;export;

Can anyone help me for Compatible Data types in .net for Delphi Data Types.. My Second Question IS

How to pass Unicode Data from .net and How to receive it back from Delphi DLL.

Thanks in Advance..

I have never failed,I just found 1000 ways that never works. Regards, Victory.
